Replace the capital letter sections with specific values and then restart Hadoop.

Expand the Oozie hadooplibs tar.gz
in the same location Oozie distribution tar.gz
was expanded. A
*hadooplibs/* directory will be created containing the Hadoop JARs for the versions of Hadoop that
the Oozie distribution supports.

The ExtJS library is optional (only required for the Oozie web-console to work)

IMPORTANT:
all Oozie server scripts (=oozie-setup.sh=, oozie-start.sh
, oozie-run.sh
and oozie-stop.sh
) run only under the Unix user that owns the Oozie installation directory,
if necessary use sudo -u OOZIE_USER
when invoking the scripts.

Create a libext/
directory in the directory where Oozie was expanded.

If using a version of Hadoop bundled in Oozie hadooplibs/
, copy the corresponding Hadoop JARs
from hadooplibs/
to the libext/
directory. If using a different version of Hadoop, copy the
required Hadoop JARs from such version in the libext/
directory.

If using the ExtJS library copy the ZIP file to the libext/
directory.

Run the oozie-setup.sh
script to configure Oozie with all the components added to the libext/
directory.
